Third angle projection is in common use in the USA, Canada, and the UK. The rest of the world more commonly uses first angle. There is no inherent superiority of one projection over the other. When you are making drawings that may be used internationally, it's a very good idea to indicate by a small symbolic diagram which projection is in use. This diagram is usually a side and end view of a truncated cone.

One ton =12,000 btu's. A 5 ton unit would provide 60,000btuh of cooling. lc Refrigeration is the ability to remove heat. Like anything else distance,weight, temperature etc. there is a need to measure it. Tonnage is the unit of measure used to express refrigeration capacity.

i just asked that question df .-.

EGR or Exhaust Gas Recirculation is a system that takes exhaust gas and recirculates it back into the intake air, this does a few things beneficial to the actual running quality of the engine such as: Reduce Combustion Temperatures which dramatically cuts down on Spark Knocking (detonation) which is a common occurance on a high-compression engine such as the LT1, and reduces the NOx (oxides of nitrogen) emissions caused by high compression which fails emission tests.

Two interconnected hydraulic cylinders can seen as a lever, the smaller cylinder is the end of the lever further away from the fulcrum (where you will apply the force), the larger piston is the load end. Add to that another lever (a brake pedal), you again increase your mechanical advantage. So, at least one of the reasons why hydraulic systems have large mechanical advantages is they combine multiple simple machine concepts to multiply force and torque.

There are many softwares in the market today for Sheet metal work. I have experience with a few of them. But till date the best sheet metal softwares I have ever used considering factors like user friendliness, cost effectiveness, etc. MetaCAM by Metamation is the best one.

You can find more information about MetaCAM sheet metal software in Australia and New Zealand by visiting www.nccs.com.au

A: Overload is a term used to describe a condition whereby a circuit is overstressed by additional loads imposed to it. Overload can be as small quantity or a very big quantity it depends on the circuit as it is stressed.

PWHT is a form of stress relief, other forms can be as simple as smacking your structural weld with a hammer. PWHT re-aligns metallic molicules (face centered) to similar configurations as before rapid heating and cooling occured.

Originally they were, but since the time of the industrial revolution they've been machine-made.

In tube making by pilgering, it is possible to reduce wall thickness as well as diameter of the tube. Q factor is defined as the ratio of wall thickness reduction to diameter reduction. The value of Q can be adjusted in the manufacture of tubes by changing the conicity of the mandrel. In the case of zirconium, the single crystal is anisotropic being of hexagonal close packed structure. Poly crystalline zirconium is not anisotropic, but develops a preferred oreintation after cold work. Deformation takes place by prismatic slip and by twinning. When the Q factor is maintained high, that is, when wall thickness reduction is much more than diameter reduction, the crystals take radial positions in the wall thickenss of the tube. When the Q factor is low, the crystals take tangential positions In nuclear applications of zirconium, in the event of hydriding, the hydride forms perpendicular to the c axis of the hcp crystal. A high Q factor leads to tangential hydride platelet formation, which is acceptable. High Q factors are achieved in pilgering. A low Q factor leads to radial hydride platelets in the thickness of the tube and hence has deleterious effects. Low Q factors occur in drawing process. Hence for nuclear applications, high Q factors through pilgering are used. Balakrishna Palanki Ph.D

The powertrain control module is one of the electronic control modules used on a vehicle. Others include antilock brake, airbag, transmission, body,

Neither. Pneumatic equipment uses air, under pressure, to convey mechanical energy from one place to the other. Hydraulic equipment uses water for the same reason. A hot-air balloon uses less dense hot air to fill it's balloon. Due to gravity the more dense cold air sinks down and pushes the hot air filled balloon up. The burner uses a mechanical arm with a spring (with a string and handle attached) to control the amount flame.

The hotter the steam the higher the energy in the steam and the more energy to be transformed to mechanical motion.

There isn't one. The closest is adze.

Hydraulic rock breakers are powerful percussion hammers. The rock breaker works on the principal of hydraulics, where putting pressure on one part of a fluid transfers pressure to all areas of the fluid, allowing a multiplication of force.

an electron tube containing a near-vacuum that allows the free passage of electric current.

Welding gas can refer to two things. In torch welding, it is either a fuel gas such as acetylene or MAPP or oxygen, and in arc welding (MIG, TIG, etc...) it refers to any of the inert gases such as carbon dioxide or argon that is pumped over the weld pool to protect it from atmospheric contaminants.

trebuchets originated in china around 300 BC and was used all the way through the 14 century until eventually gunpowder made it obsolete.
